Open Tubular (Clincher)An open tubular is constructed using the same casing and tread materials and process as a tubular, but instead of sewing the casing together (closed), the sides of the tubular casing are folded around aramid fibre cords to produce beads. This ‘open’ design performs like a tubular, yet conveniently mounts like a standard clincher tyre.

If combined with a Latex inner tube the ride becomes even closer to that of a tubular, offering excellent traction and cornering, low rolling resistance and shock absorption.

About Cyclocross Tyres

Cyclo Cross tyres are for use with road wheels to allow them to be ridden off road. They range from 30 to 35mm wide and are designed with different tread patterns to suit the various conditions that can be encountered during the Cyclo Cross season. Usually at the start of the season the ground is dry and hard so a narrower low tread tyre is needed as low rolling resistance is a priority. Later in the season when the ground is wet, grip is a priority so a wider tyre with increased tread would be the better option.

About the Challenge brand

In 2003 Challengetech created its own brand “Challenge”. Challenge, as the word says, wants to point out how difficult and exciting it is to keep the tradition of high quality products, created with obstinacy, with the steady research of special materials and through handcrafted processes.
Since the 2000s, Challengetech has being producing tubulars for other brands, thanks to the constant use of these products in the professional cycling.

Super supple cx clincherversatile fast rolling with superb shoulder grip. Nice size & volume where cushions rough terrain and will operate at low pressure below 20psi if required. Not tubeless ready or compatible as porous sidewalls. Reasonable weight at just over 300grams.
The rubber compound is very grippy and resilient to cuts, very few punctures.
Used for 2half cx seasons (this is the second tyre as first the tread became unbonded after 6months otherwise would have given 5stars)
This tyre excels on dry/slightly wet grass and light mud. Both off-camber and banks,descents gives good control when light to intermediate conditions. Obviously not good on the rear when you need traction (ie steep climbs or wet/muddy).
Certainly recommended as a lot faster than mud tyres in light conditions.

Fast lighweight tyreBought this for the spring/ summer on my cross bike. Just completed a 100K ride on them over a mixture of on/off road and they roll great and handle the bumpy stuff well. Used them through the local woods and you get a nice compliant ride at about 35-40PSI. Use them with Challenge latex tubes and no punctures so far.
Plan to do the Wiggle SDW 100 mile cross challenge later this year on them and so far think they will be a great choice for this event.

*Nice tires - capable over a variety of surfacesAs usual for Challenge, nice supple casing - smooth, comfortable and fast rolling. The tread is not so big as to cause issues on asphalt - these don't squirm in the same way a grifo does on the road. I have been pleasantly surprised by the traction on wet / muddy grass. If you don't have the clearances for anything bigger - these are a good bet for a XC bike that you are going to ride quickly on the road, but don't want to give up too much grip when you get off road. A nice compromise.

For Racing OnlyYou might think this is a bit pricey for a clincher until you give them a proper go in their natural environment. On dry grass, hardpacked dirt and tarmac they are superb. I'd expect them to rock on snow and ice too. They are fast rolling and corner well thanks to the chunky side knobs. You don't get the security or resistance to pinch punctures of a tubular, but running on bumpy, dry grass at 25 psi felt pretty secure. The downsides are that braking and rear wheel grip are rubbish on loose or slippery surfaces, but use these for racing in the conditions they are designed for and you won't find a better clincher.

Hi I'm looking for a fast semi slick tyre for my 29er mountain bike for commuting, off raid paths etc this looks to fit the bill but will it fit my 29er rims? I also don't know what open tubular means ? Does it need an inner tube or is it a tubeless tyre? Please advise. My bike is a trek x calibre 8 if that makes any difference.

Asked by: Mooseington

It'll fit 29er rims but is probably more at home on narrower rims - up to 23 mm or so. 'Open tubular' means it uses the same flexible material for the carcass as a tubular, but in a clincher form with beads so you need a tube and you can't seal them for tubeless use. They're a cyclocross racing tyre so they'll be fast and light but to be honest, they may be a bit skinny and delicate for commuting and everyday use.
